Your recycling bin and two views of it for labeling

OVERVIEW: 
We are going to simulate how scientists study the
past.  Scientists use layers of rock with fossils to
understand the past. 
(These layers of rock are called'STRATA')

OBJECTIVE(s):
1  Relative of Rock layers 
(Oldest deposited on bottom)
2  Describe objects in trash as events occurring 
through   time
3  Fossil record is in 3-D
4  Collection of accurate data is critical

ACTIVITIES AND PROCEDURES:
1    Divide into groups
2    Each group will be allowed to excavate ___cm of paper
     from the recycling bin.  Each group assigned a
     different layer of paper. 
Try to learn as much as you can about your layer.
3    Record data on the outline given.  There is a top view
     and side view of the recycling bin.  Facts that may be
     useful:  subject, dates, teachers names, position of
     paper, type of paper, Xerox or ditto.
